#2 Clemson Tigers (15-0)

CLEMSON, S.C. (AP) Half of Clemson's talented defensive front four participated in the Tigers pro day Thursday before evaluators from all 32 NFL teams.

While defensive ends Clelin Ferrell and Austin Bryant did not take part in drills due to injuries, tackles Christian Wilkins and Dexter Lawrence showcased the abilities that have them on track to be first-round NFL draft picks next month. The linemen, nicknamed the Power Rangers after the popular children's heroes, met NFL officials, including three head AFC coaches: Pittsburgh's Mike Tomlin, Tennessee's Mike Vrabel and Cincinnati's Zac Taylor.

The four linemen, all part of Clemson's two national titles the past three seasons, wore different color headbands during the session that synched up their favorite Mighty Morphin heroes.
